I'm looking at the docs for recv() on perldoc.com, and I am unsure as to what I am seeing/reading. The docs indicate that the SCALAR will shrink or grow as necessary, regardless of LENGTH specified.

However, I have noticed that by specifying a nessage length, the message gets truncated (is that the right word?) to LENGTH. Example:

my $msgLength = 12;

# send_client is the length of the incoming message.
my $send_client = recv( $client, $message, $msgLength, 0 );

Am I missing something in this code? I'm assuming this truncation is correct, but what does recv() actually do with these parameters? Is there a way to dynamically increase the size of LENGTH? Or is it always fixed to a certain byte size?

Thanks

If you make something idiot-proof, eventually someone will make a better idiot.
